Properties of flint, physiological effects, zodiac signs and flint jewelry.
Flint is a hard rock, a form of microcrystalline mineral quartz.
It occurs mainly in sedimentary rocks such as limestone. The flint is usually glassy or waxy in dark gray, brown, black or green. Flint is one of the defining materials of the Stone Age. When struck on steel, flint gives enough spark to ignite the fire with a flammable material. The artificial materials used to make sparks in lighters were also called flint (or chert).
